[lamsijan]

your overclock went bad. happens to the best of us. that's how we find the limit of our hardware. just go backto previous settings via booting to windows' safe mode or just reseting the PC as the case may be (I don't think you have to a system restore, am I right, community?).

 

and when overclocking, I think I speak for everyone, when I say always tweak one option at a time! never two or more! that way at least you'll know what happened when it stops working.

 

I might be wrong but I think 780 might not have been a good number. http://www.pcgameshardware.com/aid,696250/...Reviews/?page=4 775 is stable according to these guys. you might want to increase the speed by smaller increments too. and BTW that temp? 56? that isn't under load, is it? if you want to test stability and temp at same time download rivatuner and furmark. furMark will really put a load on the card and heat it up but good. try to keep it below 70 for longevity.

 

best of luck

System restore won't do anything to an overclock i think, just reset the BIOS, or bring down the clocks a little from there.

For graphics; windows safe mode and disable the overclock.
